UFAGTURE OF AMYL ACETATE AND ITS HOMOLOGUES FROM CHLOE-HYDRO No Drawing.

To all whom it may concern:

drocarbons having more than one carbon.

atom.

It is known (see Schorlemmer Licbigs Annalen, 1872, vol 161, p. 264. lines 2730) that in the decomposition of chlor-compounds of the paraflin hydrocarbons having more than one arbon atom with alkali acetate in the presence of acetic acid, large volumes of amylenes are produced, whereby the yield in amyl acetate is reduced.

Now I have found that by the use of fused alkali acetate and acetic acid in the presence of sodium or potassium sulfate the formation of amylenes is decreased and a yield of 65% of the theoretical by Weight of pure amyl' acetate of a, boiling point 120148 C. is produced.

More than a Very small water content in the alkali acetate is prejudicial and leads to the increased formation of amylenes.

The following charge is used:

100 parts by weight of chlorpentane 72 alkali acetate 1 acetic acid 1 sodium or potassium sulfate.

CA RIBOINS OF THE PARAFFIN SERIES.

Patented May 6, 1919..

Application filed January 22, 1918. Serial No. 213,250.

The charge is heated from 8-14; hours under pressure and a temperature of 195 C. in a mechanically stirred acid .resisting autoclave.

The esterified product may be removed by.

distillation under pressure from the retort.

What we claim is: l. A method of esterifying chlor-hydrocarbons of the parafiin series which consists in treating the chlor-hydrocarbons with an alkali acetate and acetic acid in the presence of a sulfate of an alkali metal.

2. A method of esterifying chlor-hydrocarbons of the parafiin series which consists in heating under pressure the chlor-hydro- GEORGE G. OBERFELL. HUGH T. BOYD.
